I am working on a project for WashU, and we are building a helicopter to fly itself. I want an onboard computer processing flight stability algorithms from various sensors, and I want it to take flight direction commands from a laptop via a radio device.
12 x ADC inputs (environment sensors) (including proximity)
4 x PWM outputs (servo control)
1 x I2C data transfer (compass sensor)
1 x support for bluetooth or other radio device
Looking around, Where I come up really short is on the ADC. Are there shields for extra ADC channels? The device needs to be very light weight because its on a cheap helicopter.
What do you suggest? I have been all over SparkFun and Parallax BS trying to find something useful for under $200. The closest ive come is a Basic Stamp with a Toothpick.
Thanks for your help,
